To all whom it may concern:

Be it known that I, IRA H. SPENCER, a citizen of the United States, and a resident of Hartford, in the county'of Hartford and State of Connecticut, have invented a new and Improved Valve, of which the following is a specification.

My invention relates more especially to that class of valves employed for closing the mouth or opening to the tube of 'a pneumatic system, and the object of the invention is to provide a device of this class that shall be extremely simple and effective in operation andone that may be produced at a minimum cost of construction.

One form of device in the use of which the objects sought may be attained is illustrated in the accompanying drawings, in which- Figure 1 is a view in longitudinal section through the intake end of the pipe of a pneumatic system showing my improved.

valve attached thereto, the nipple being broken. Fig. 2 is a face view of the same.

Fig. 3 is a View in cross-section on plane denoted by line 3-3 of Fig. 1. Fig.

1 is a view similar to Fig. 1 but showing the valve in its unlocked position. Fig. 5 is a. view in section on plane denoted by line 55 of Fig. 4. Figs. 6 and 7 are side views of a nipple illustrating the manner of use of my improved collar.

In valves of the class herein shown and described it is very material that the mouth or inlet to the pipe or tube controlled by the valve shall be effectually sealed when not in use and a valve having means for locking it in its closed position will aid in attaining this result, 'the means for operating the lock being thus not readily at the hand of unauthorized persons. As a further means of enabling the valve to effectually seal the mouth the valve is provided with a more or less flexible material arranged tov rest upon the valve seat, and this packing should also be provided with means to prevent its distortion under the unequal pressures which it sustains, which distortion wouldcause the packing to wrinkle at the valve seat and thus allow leakage at this point.

The valve herein shown and described is provided with means for overcoming all. of these objections. and at the same time. the valve embodies a minimum number of. parts of simple construction to attain the results desired.

In the accompanying drawings the numeral 6 denotes a mouth-piece or nipple-arranged to be secured to the end of a pipe or tube of a pneumatic system in which air is drawn in to the mouth. This mouthpiece has an inlet chamber 7 in which an annular groove 8 is formed. A'lip 9 extends about the edge of the opening or mouth to the chamber 7, this lip constituting a valve seat.

A lug 10 projects upward from the mouthpiece, this lug forming a knuckle for the reception of a pintle 11 upon which pintle a .valve is pivotally mounted. This valve has ears 13 located at the opposite ends of the knuckle 10, which ears receive the ends of the pintle 11. p The valve consists preferably of a plate 12' of proper size and shape to cover the ;opening into the chamber 7, a cup 14 secured to the inner face of the plate and 5a packing 15 located within and held by said cup, this packing being disposed to rest against the lip or valve seat 9 to secure the opening into the chamber 7. A hearing stud projects through the valve, this stud consisting of two sections, an outer section @16 having a flange 17 resting against the outer face of the plate 12 and an inner sec- ,tion 18 secured to the outer section as by means of inter-engaging screw-threads.

A pin 19 is secured within an opening in the outer section 16 of the stud, the outer end 20of this pin being formed to receive a device for turning the stud in its hearing. The connection between the two sections of the stud may be of any desired construction, and 1n fact, 1t is not absolutely essential that this stud shall be formed in sections. When this'form of a stud, however, is used the connection between the two sections will be such that a supporting plate 21 is clamped between the two sections. The pin 19 may be secured within the stud in. any desired manner. The plate 21 rests against the inner face of the packing 15 and serves to maintain the packing flat and prevent it from distortion under the unequal pressures, the packing being thus retained in place and prevented from wrinkling, which wrinkling would allow the valve to leak.

In order to secure the valve in its closed position a lock is employed, the plate 21 being formed to in part constitute the lock and being in fact a locking and supporting plate. The plate is of circular form to bear against the packing at substantially uniform distances from its outer edge at all points about the edge, and is eccentrically mounted upon the stud. The stud is also eccentrically mounted with respect to the chamber 7 so that as the stud is turned the plate will be moved toward the edge of the valve and caused to engage within the groove 8. While this will throw the plate 21 slightly off from the center of the packing, this movement will not be suflicient to prevent the plate serving its full func tion as a support for the packing.

Various forms of construction of the plate to enable it to engage'within the groove 8 may be employed, in the preferred form of construction an offset flange 22 extending about the edge of the plate being employed. A semi-circular slot 23 is formed in the plate in which a locking pin 24 from the valve projects, the engagement of the pin within the slot limiting the turning movement of the supporting plate and lock. WVhile the mouth-piece is shown and described herein as a separate part it need not necessarily be so formed, as it may constitute the end of a pipe as a whole, and other details of the construction may be departed from to a greater or lesser extent without avoiding the invention. lVhile the plate 21 may be secured to the stud by means of the frictional connection between the two stud sections, yet in order to secure its positive connection with said stud a key 25 extending from one of the stud sections into the plate may be employed. In the construction of devices of this character the nipple or mouth-piece 6 is usually secured to a T or like connection forming a part of a system of pipes located within the wall of a building. In erecting such piping, owing to lack of care or for other reasons the Ts are liable to be located at various distances from the face of the wall. The opening in the wall through which the nipple extends is usually covered around the nipple by a collar. In order to provide for a nipple of minimum length to suit these various conditions as to location of Ts and also to lessen the appearance of undue projection of the nipple I have provided a finish collar 30 which is movable on the nipple. In order to produce the desired result as to adjustment this collar is of substantial cup-shape and has a hub 31 interiorly threaded to fit the threaded surface 32 of the nipple, and a flange 33 is formed to rest against the outer face of the wall through which the nipple'projects. When a T is located very close to the face of the wall the collar should be used as shown in Fig. 6, while when the T is located at a considerable distance from the face of the wall, the collar is to be used as shown in Fig. 7. Under these extreme conditions it will be seen that, with the use of my improved collar, the nipple may be of a minimum length, and that the collar may be placed against the face of a wall and located with respect to the nipple at any point between the lines ab.

In Fig. 7 the nipple terminates with its outer end within the confines of the wall,

and it will be seen that by reversing the collar as here shown I am still enabled to use the same to produce a plain smooth-finish closure for the wall opening, the front face of which may be at any point longitudinally of the nipple within the limits of the collar adjustment.

My invention relates more especially to the class of pneumatic systems in which numbers of outlets are employed, such for instance as in the case of pneumatic systems used for suction cleaning and for other similar purposes, but it will be understood that the invention is not limited to use in a pneumatic system designed for any special purpose.
